Temp&Hum 18 Click Board™

Product Code: MIKROE-4892

How Does The Temp&Hum 18 Click Board™ Work? The Temp&Hum 18 Click Board™ as its foundation uses the HS3003, a highly accurate, fully calibrated relative humidity and temperature sensor from Renesas. The humidity can be measured within a range of 0 to 100%RH, while the temperature sensor is designed for a range of -40 to +125°C. The typical accuracy for humidity is ±2.5%RH in the measuring range of 20 up to 80%RH at ambient temperature, and ±0.25°C for temperature between 0 to +70 °C with very low power consumption. The HS3003 digital sensor accurately measures relative humidity and temperature levels. The measured data is internally corrected and compensated for accurate operation over a wide range of temperature and humidity levels, which brings us to its highlighted feature - user calibration is not required. The entire output consists of only four bytes of data; that's why calculating the corresponding relative humidity in percent and temperature in degrees Celsius is very easy. The Temp&Hum 18 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Standard Mode operation with a clock frequency up to 100kHz and Fast Mode up to 400kHz.

The HS3003 is also factory-programmed to operate even in Sleep Mode. In Sleep Mode, the sensor waits for commands from the MCU before taking measurements and only performs conversions when it receives a Measurement Request command; otherwise, it is always powered down. The Temp&Hum 18 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the I2C communication lines properly. However, the Temp&Hum 18 Click Board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
